PUMP-MOTOR.

SPECIFICATION forming part of Letters Patent No. 519,608, dated May 8, 18.94.Y

. Application filed January 3.1894.. sesam. 495,550. (Nomad.)

To a/ZZ whom it may concern:

Be it known that I, LOUIS HENRY LLOYD, a

citizen of the United States, residing at Lincoln, in the county of Logan and State of Illinois, have invented certain new and useful Improvements in Pump-Motors, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of my improved motor.A Fig. 2 is a plan view thereof, the vertical Ways being shown in cross section, and Fig. 3 is a detail horizontal section hereinafter described. Fig. 4 is a detail side elevation showing the parts in a different position from that shown in Fig. 1.

This invention relates to a motor or mechanism for vertically reciprocating pump-rods, the design of it being to provide simple mechanism for utilizing the gravitating force of a suspended weight for imparting a regular movement to the pump-rod, the yspeed and regularity of the mechanism being governed and assisted by the swinging motion of a pendulum, as hereinafter fully described.

In the drawings annexed, the numeral 1 designates a suitable frame which supports a pair of vertical ways or` guides 2,- between which is adapted to vertically work a suitable weight 3. Attached to the weight is a cable 4, which passes up over a pulley 5, journaled at the upper ends of the ways, and then down and around a drum 6 secured Yon a shaft'7 Ijournaled in said frame-1. n

Secured on shaft 7 is a spur-gear 8, which meshes with a pinion 9 carried by a shaft 10, journaled above said drum, said shaft 10 being operated to wind therope or cable upon the drum by means of a sprocket-wheel1l secured on one of itsends, this sprocket-wheel carrying a sprocket chain 12 which also'passes over a smaller sprocket-wheel13 secured on a stub-shaft journaled in the frame below., The

. sprocket Wheel13 and the chain are driven pending lweighted-.arm 17 extending belowv by means of ahand-crank removably secured on theend of the stub-shaft. v

Secured rigidly on the shaft 10 is a ratchet wheel 15, and pivoted on the frame adjacent Vto this ratchet wheel is a hook-pawl16 which extends over the upper edge of the ratchet wheel and vis normally kept outof engagement with the teeth thereof by means of a dethe ratchet wheel and normally resting on a stop 18."` l y Pivotally swung on shaft 10 in front of the ratchet wheel is a pendulum 19, whose upper end extends above the ratchet wheel and carries a pivoted pawl 20, which is provided with anvupwardly extending weighted arm 21. An adjustable stop 22 is secured on the upper end of the pendulumv and extends into the path of the throw of said weighted arm 21 and serves to limit its movement. pendulum below the ratchet wheel is a lateral arm 23 which is adapted to come in contact with the weighted arm 17 of pawl16 at a predetermined point inthe swing of the pendu-` lum, said arm being adj ustably secured to the pendulum inorder that it may-be set so as to v strike the weighted arm atthe proper instant.

Carried by the pendulum and working on the end of shaft lO, in front of the ratchet wheel,

lis a sleeve 24 which carries at its outer end a lateral arm 25, which Yis provided with a series of holes to enable it to be adj ustably connected to the pump rod 26. It will be observed that the tendency of the Weight 3 is to rotate the 'ratchet Wheel 15in the 'direction of the arrow thereon, through the medium of the cable and the train of gearing, the rotation of the ratchet wheel being prevented by pawl20.

To start the mechanism it is simply necessary to start the pendulum to swinging, which may be done by taking hold of the pendulum with the hand or by means of the crank and sprocket chain. As the pendulum swings to Carried by the t-he righ t, arm 23, carried thereby, at the proper instant strikes arm 17 and engages pawl 16 with the ratchet-wheel and thereby locks the v ratchet wheel against rotation; aspsoo'n as pawl 16 engages the ratchet wheel it releases pawl 20 from the pressure of the ratchet wheel,l whereupon the weighted arm 21 falls against stop 22 by gravity and therebydisengages said pawl 20. The pendulum is then free to swing toward the left, in which movement it is assisted `by the dropping or falling of the pump rod; as the pendulum swings to the left the pawl 2O is automatically thrown back into engagement 'with the ratchet wheel by means of the weighted arm`21 as soon as the pendulum passes the center. When the pawl 2O thusfalls into engagement with the ratchet Wheel it strikes the same with sufficient force IOO to relieve for an instant the pressure against pawl16, whereupon said pawl 16 automatically and quickly swings up out of engagement with the ratchet wheel, thereby permitting the force exerted bythe ratchet Wheel through the medium of pawl 2O to swing the pendulum to the right and lift the pump rod. These operations are repeated, as the pendulum swings back and forth, until the weight reaches the limit of its downward movement. When the desired quantity of water is pumped, the operation of the mechanism is stopped by taking hold of the pendulum and holding it still an instant. It may be started again at any time by giving the pendulum a sufficient swing to the let't to relieve pawl 16 and let it swing up out of engagement.

In order to increase the storage of power and thereby render the pump self-operating for a greater length of time, the machine may be so arranged that the weight may pass down into the well or into an opening at the side of the Well, as is evident. In this way sufficient power may be stored up to last a comparatively long time, according to the quantity of water used.

It will be observed that the specific construction of the parts maybe varied without departing from the spirit or scope ot` the invention.

Having thus fully described my invention, what I claim is l. In a device for imparting a reciprocating movement to a pump-rod or other device, the combination of a frame, a gravitating weight, a drum and cable connected to said Weight, a ratchet Wheel driven by said drum, a pendulum pivotally mounted adjacent to said ratchet wheel, an automatic pawl carried by said pendulum and movable thereon and engaging the ratchet wheel, whereby the force exerted by the ratchet wheel is communicated to the pendulum, an arm connected to the pendulum and adapted to be connected to the pump-rod or other device, and means carried movement to a pump-rod or other device, the

combination of a frame, a drum journaled thereon and a cable and weight for operating said drum, a ratchet wheel driven by said de` vices, a pendulum swung concentrically with said ratchet wheel and extending above the ratchet wheel, a weighted paWl carried bythe pendulum and adapted to be thrown in and out of engagement with said ratchet wheel as the pendulum passes the center, a pawl pivoted on the frame and normally held out of engagement, devices for forcing said pawlinto engagement with the ratchet wheel to relieve the pressure against the other pawl, and an arm connected to the pendulum and adapted to he connected to the device to be operated, substantially as described.

3. In a motor for operating a reciprocating part or device, the combination of a drum and devices for imparting rotation thereto, a ratchet wheel driven by the drum, a pawl 16 provided with a depending arm 17 to normally hold it out of engagement with the ratchet Wheel, a pendulum swung concentrically to the ratchet wheel, an arm 23 carried by the pendulum and adapted to strike said arm 17, a Weighted pawl 2O pivoted on the pendulum and normally engaging the ratchet wheel, and an arm connected to the pendulum and adapted to be connected to the device to be operated, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
